<h3>What is Unitary method?</h3>
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Cindy's shadow is 5 feet.
length of the shadow of the pole at the same time, she finds it to be 12.5 feet.
So,
12.5/5=x/5,
62.5=5x
x= 12.5 feet.
Hence, the height of the pole is 12.5 feet.

The number of students who received the paint can be expressed as;
Initial quantity of paint=Quantity per student×number of students
where;
Initial quantity of paint=5/7 gallons
Quantity per student=1/7 gallons
number of students=n
replacing;
5/7=(1/7)×n
n=(5/7)×7
n=5
The number of students who received the paint=5 students
